At first the two record their own videos, explaining that they’re on their way to the first script reading for “Radio Romance.” However, when Yoon Doojoon and Kim So Hyun are alone together, they become adorably awkward.

In order to become comfortable around each other, they prepare a few quizzes for each other. One is to test their synchronicity by seeing if they both answer the same thing. They started off on a good note but quickly started to diverge in tastes – although the quiz opened them up to talk more about themselves.

Then they started asking the other quiz questions about themselves, to test their knowledge of each other. Yoon Doojoon got many of the basic questions about Kim So Hyun right (he said he looked her up online) but was very confused by some of her personal details.

Kim So Hyun started off on the wrong foot by getting the number of Highlight members confused, but quickly righted herself for the next few questions (though Yoon Doojoon accused her of just randomly guessing). However, she ended up getting more questions wrong in total, which meant she had to do a cute punishment.
